This species is known from northeastern coastal China (in the
provinces of Hebei, Beijing, Nei Mongol, Liaoning and Shandong), north and
central Lao PDR, and just across the border into north central Thailand.
In Japan, there are only three records, all of vagrants, on Amami-oshima,
Kuchinoerabu Island, and Yoron Island (Kagoshima Prefecture) (Abe et al. 2005).
Records from Lao PDR were originally identified as T. teniotis and are
assumed to be T. latouchei based on range.
Countries: Native:
China; Lao People's Democratic Republic; Thailand
Vagrant:
Japan

Population:

It is probably locally rare, as usually only a single specimen
is ever collected. One large colony is known from Lao PDR. The record from
central Lao PDR was purchased in a market (C. Francis pers. comm.). It
presumably originated nearby. Three specimens have been found in Japan, after
the type was recorded in China 1917.
Population Trend: Decreasing

Habitat and Ecology:

This species roosts in caves, and forages in the surrounding
forest. In Thailand it has been recorded from dry evergreen forest at 1,500 m
asl, on top of a mountain (S. Bumrungsri pers. comm.).
Systems: Terrestrial

Major Threat(s):

Disturbance of the cave habitat of the species is a potential
threat, including mining. In some parts of its range, such as northern Lao PDR,
it is known to be trapped for food and this may be occurring in other parts of
its range.

Conservation Actions:

The known locality in Thailand is in a protected area, Phu
Luang Wildlife Sanctuary (S. Bumrungsri pers. comm.). It is not known
whether it occurs in any protected areas elsewhere in its range. Further
information is needed on the range, ecology and threats to this poorly known
species. It is listed as Data Deficient (DD) in the Japanese Red List (2007).
